Functionalized heterocyclic zinc reagents are easily aminated by an oxidative amination reaction of zinc amidocuprates prepared from various lithium amides. For the oxidation step, PhI(OAc)2 proved to be the best reagent. The required heterocyc

A series of 1-dialkylmino-1-butyn-3-ones were obtained, and their reactions with hydrazine and its alkyl, aryl and unsymmetrical dialkyl derivatives were studied.The reactions with unsubstituted and monosubstituted hydrazones lead to the formation of heterocyclic compounds of the pyrazole series, while the monosubstituted hydrazines form two isomeric products.Unsymmetrical dimethylhydrazine adds at the C1-carbon atom with the formation of compounds containing an open structure.
